Duration: 1 hour
Type of activity: online quiz
Material required: a computer or a tablet
With this activity, participants will discover what Argo floats measure and why scientists need them. They will also be able to learn how floats sink and drift in the ocean and their life cycle.
This activity contains a video followed by four sections of questions. The first section concerns floats in general. The second focuses on measurements of pressure, temperature, depth and salinity. The last ones deal with the comparison of temperatures collected by floats along the same longitude and latitude.
